The micrometer includes a sleeve provided with an at least partially threaded inner surface and an at least partially threaded outer surface. The outer surface includes at least one deformable, tapered portion. A micrometric screw is engaged in the sleeve, and is able to be set in rotation with respect to the sleeve in such a way as to displace itself along the longitudinal measuring axis (x) of the device. A nut is engaged on the external threading of the sleeve and is able to be put in contact with the tapered portion in such a way as to deform it in order to adjust the play between the screw and the sleeve. The tapered portion is devoid of longitudinal slits; its deformability is provided by an external diameter variable along its periphery, preferably by an odd number of flat segments.
